Ajish Koshy d6f6f945e8 scsi: pm80xx: Enable upper inbound, outbound queues
[ Upstream commit bcd8a45223 ]

Executing driver on servers with more than 32 CPUs were faced with command
timeouts. This is because we were not geting completions for commands
submitted on IQ32 - IQ63.

Set E64Q bit to enable upper inbound and outbound queues 32 to 63 in the
MPI main configuration table.

Added 500ms delay after successful MPI initialization as mentioned in
controller datasheet.
